'WILLIAM J. I-IUSTON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF TWO-THIRDS TO THOMAS N. SUBERS AND JACOB G. SHARP, BOTH OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 438,925, dated October21, 1890.

Application filed August 21, 1890. Serial No. 362,642. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM J. HUSTON, a citizen of the United States,and a resident of Philadelphia, Pennsylvania, have invented certainImprovements in Car Couplings, of which the following is aspecification.

One object of my invention is to provide means for readily raising orlowering the protive view of part of the car and coupling, and

Fig. 3 is a sectional plan view of the coupling with part of the carstructure shown in dotted outline.

A represents part of the framework of a car, and secured to the underside of said frame is a saddle or stirrup B, in which is guided a rod D,which constitutes a combined draft and bumper rod, a coiled spring Ebeing confined between opposite washers a on this rod, so that thespring will be compressed when the rod is subjected to either draft orpushing strain.

The rod D has a fixed head F, within which is pivoted by means of apin 1) the stem or shank G of the coupling-head, the latter having atthe outer end a hook (I for engagement with the hook of a like couplingon the adjoining car. Lateral movement of the hook to effect coupling iscaused by the action of a spring f, bearing against the stem G, andmovement in the opposite direction to effect uncoupling is effected bythe action of a rod g, carried by an arm h on a vertical shaft 1', whichis adapted to suitable bearings at the end of the car, this shaft beingprovided with any of the usual means for operating it either from thetop of the car or from either side of the same.

It should be understood that the rod D has lateral play in the saddle orstirrup B to permit of a lateral movement of the couplinghead sufficientto effect coupling or uncoupling.

To suitable bearings m on the under side of the platform of the car isadapted a transverse rod J, and secured to or forming part of the latteris a block J, having a cam-slot at, through which passes the front endof the stem or shank of the coupling-head, so that by moving the rod Jto the right or left the coupling-head will under the action of thecam-slot m be raised and lowered, so as to provide for coupling with anadjoining higher or lower car. In the back of each head 01 is formed arecess a1, and projecting from the back of the head above and below thisrecess are perforated lugs tfor the reception of a coupling-pin when thecoupling has to be effected by means of a link, as shown by dotted linesin Fig. 3.

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. The combination of the shank of the coupling-headwith a transversely-movable block or plate having a cam-slot'for thereception of said shank, whereby as the plate is moved in one directionor the other the coupling-head will be raised or lowered, substantiallyas specified.

2. The combination of the coupling-head and its shank, the draft andbumper rod having a head to which said shank is pivoted, a

spring acting on the shank to move it in one direction, a shaft havingan arm acting on the shank to move it in the opposite direction, and atransversely-movable block having a cam-slot for the reception of theshank, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM J. HUSTON.
